A marine biologist is examining the effects of oil pollution on a population of birds known as seagulls (Larus canus). She is particularly concerned that oil pollution may reduce the number of eggs raised in a seagull nest. During one breeding season, she counted the number of eggs present in a sampling of six seagull nests near each of the 14 refineries throughout the state. She discovered that seagulls laid and raised an average of four eggs per season. To confirm her hypothesis, the researcher must now examine seagull nests that have not been exposed to oil pollution. The researcher believes she is correct, and so expects to find D) 4-6 eggs per nest.
Answer:
B. 0 m
Explanation:
From the position - time graph, the object would have traveled a distance of 0m after 6s.
The graph shows a decrease in distance traveled with increasing time.
- the y - axis is the position of the body
- the x - axis is the the time taken
If we trace up the time taken to the curve, the position will be 0m.
Therefore, the position of the body after 6s is at 0m.
